The brain is divided length wise, straight down
the middle, into two halves known as the cerebral hemispheres. As shown in the figure above there is a left side
and a right side, both in which hold different functions.

The Right Side: This is the side that is responsible
for art, music, intuition, spatial abilities, face recognition, colour and imagination.

The Left Side: This is the side that is responsible
for or logic and reasoning. This falls under categories such as language and math.

Because there are two different hemispheres, there
needs to be a way way for them to communcate with each other. This is where corpus callosum comes in.
The corpus callosum is a bundle of nerve cells hat allows communciaction between the two hemispheres. The
brain controls the body in opposites, as the right side of the brain controls muscles on the left side of the body and the
left side of the brain controls muscles on the right side of the body. Sensory information of the brain to is crossed over
from left and right. Therefore, damage to one side of the brain will affect the opposite side of the body.
